Possible to use percentages in Fundraising plugin, rather than fixed amounts?

Currently using Fundraising to track funding for several fundraisers on a client site. The output on a page is something like this: "$10 raised of a $500 goal"

The client would like to instead start displaying percentages, rather than dollar amounts, on the public-facing part of the site. The back-end could stay exactly the same. So instead of what's shown above, it would instead read: "2% of the goal has been raised" Behind the scenes, they'll still be tracking exactly the same way with dollar amounts, etc.

Is there a way to do this either as some PHP to do the calculation or tweak the plugin to allow for it to output in percentages?
